Abstract

The invention discloses a projector, which is used for projecting a picture. The projector comprises an upper cover, a lower cover and a door plate, wherein the upper cover is provided with a first limiting part; the lower cover and the upper cover are combined with each other and form an accommodating space; an opening is formed in the lower cover; the opening is applied to a plug for passing and is electrically connected with a socket in the accommodating space; when the upper cover is combined with the lower cover, the first limiting part is matched with the plug to limit relative motion of the upper cover and the lower cover; the door plate is connected with the lower cover; the door plate is used for selectively shielding the opening or not; when the door plate does not shield the opening, the plug is electrically connected with the socket through the opening; and when the door plate shields the opening, the door plate limits the plug to pass through the opening, so that the condition that the projector is powered off when the upper cover is separated from the lower cover is ensured. The projector shields the opening by matching the door plate to limit the plug to be inserted into the socket, so that the safety is further ensured.

Description

technical field [0001] The invention relates to a projector, in particular to a projector which is easy to assemble and disassemble and has a high safety factor. Background technique [0002] A projector light source is used to emit light to project images onto a screen. The light source is the core component of the projector, and it is also a consumable item with a certain service life. During the service life of the projector, the replacement of the light source is often encountered. The casing of the projector is usually composed of an upper cover and a lower cover. When replacing the light source, the upper cover needs to be opened. Since there is a high voltage inside the power-on projector, opening the upper cover to replace the light source in the power-on state may cause clicks, so , you need to unplug the power plug to open the cover to replace the bulb. However, it is unavoidable that the user will forget to unplug the power plug and open the upper cover, which w...
